A Basco Model 08060 Type 500 shell and tube
heat exchanger with 3/8" copper tubes was used as a lube oil cooler in
a Joy Turbo Compressor. The Joy Compressor has two Inter Coolers (plate fin,
air on shell side, water on the tube side with 5/8" tubes). The lube
oil cooler has oil on the shell side and cooling water on the tube side.
Fouling in these lube oil coolers would cause a drop in performance after
six months and needed replacement within twelve months. At the end of the
twelve month period the tubes would be nearly plugged solid.

Solution:

One Electronic Descaling 2000 unit was
installed.

The treated lube oil cooler remained in
service for over one year.

The annual inspection revealed no scale
and in good working condition after a one year period.
